Hydrofoamer pump for Vertex 150?

[spedly]

This might be a dumb question but can the 9420 pump be connected to a 9410 body? If so would this have a positive impact on skimming ability? I have a 9410 right now but it's undersized for my tank. Upgrading the pump may be a cheaper option than a brand new skimmer.

The only real upgrade is a taller cup which will let you run the air full open, the 9420 is way too much pump for the small 9410 skimmer body.

Thank you Roger. That confirms what I thought.

Hi there

I'm new to the hobby, and as I'm planing my build, I've bought an Omega 150, secondhand.
It arrived dirty, with a dead pump, so now I'm considering replacing my dead Sicce with a Tunze Hydrofoamer 9420.

I have two questions left :

- Can I use my original Vertex volute on the Tunze pump ? or will I have to mod it?

- CanI screw the Tunze pump on the pump support plate supplied by Vertex ?

Thanks a lot

The pump will include a volute, since the volute is very important to the function, by the restriction and placement of the air the water to air ratio is controlled, it is hard to say if this is a good idea or will work, generally the volute is matched to the skimmer but it is a combination of needle wheel and volute that feed the skimmer the right mix. If the pump is the newer Sicce style it should fit (i.e. the volute is secured with a screw to prevent it from spinning loose).

Sorry for reviving this thread again, but I bought a tunze 9420 to replace the original pump of my vertex omega 150 since the impellor broke. It fits pretty good but I've been unable to get the same kind of foam as I had before. The foam will rise but it's unstable and bubbles will burst sending lots of water in the collection cup. Before I had a nice thick foam and thick skimmate as well.

I tried raising the skimmer a bit but It didn't appear to help much. Can anyone help?

 

[rvitko]

Do you know how close the 9420.040 is in terms of water/air output as your old skimmer pump? If it is a big decrease or increase it is not likely to work well. Were any adapters needed or anything which could change the performance?

 

[rvitko]

From what I could find online the stock pump had only about 250 lph air the 9420 has about 600 lph. The 9410 would be closer but still stronger. The pump is too strong.

According to some sites the Vertex Omega has about 800-850lph just like the Tunze, though it's a bit different on several sites.
The connection fits perfectly so I don't think there's an issue there.

 

[rvitko]

You are correct, I had misread GPH and LPH. Do you have the old one to compare needle wheel size and pin count?

 

[AquaManiak]

I can't really disassemble it right now as it's running.
Judging from the images on the net it does look a bit different

The skimmer is still working, and gets quite a bit of crap out, it's also a lot quieter. I'm just feeling the skimmate is not as much as and definitely not as thick as before. I also have some red cyano issues since the skimmer change.

The 60Hz version of 9420 has 2.5 rows of needles, the 3rd set is cut in half. The Vertex needle wheel looks more like the 9430 pump which for 60Hz has 3 full rows of needles.

I have a similar question. I would like to replace my Sedra 5000 on my ASM G3 with either the Tunze Hydrofoamer T9420 or the T9410. Which do you recommend? I've been unable to find any specs on air or water flow on the Sedra. Thanks for your recommendation.

 

[rvitko]

It would be impossible to recommend without knowing the original air and water flow, we would need to match that closely to get good results. I also was unable to find this info.

 

[Fishingpcola]

I did find out the the Sedra 5000 output is 500 gph. Can't find the air intake specs.

 

[rvitko]

As I recall the Sedra was kind of an Eheim 1260 clone, it did not have the big volute and therefore had very limited air capacity, if I had to guess it would be about 300 gph water and maybe 150 of air. I would imagine the 500 was the water only flow rate before conversion to needle wheel. I think the closest would be a 9410 but I cannot do more than guess.

This guy used the 9410 as his replacement pump.
